This is my opinion for past, future and new hive users.
The posts don't need to add value to the blockchain !
Does this blockchain as any contract with anybody ? With who ?
The blockchain seems pretty well growing without having an extensive set of rules for posting. There is a whole ecosystem giving value to hive apart from blogging so what you are doing here is taking value from someones work / art / creation, which you can, but what is seen is that you are countering investigative work for crimes against humanity, so i consider you to be in that special category COINTEL-PRO !
Also there is stunning amounts of money in the DAO, which yes it is used to bring value to the hive blockchain, people if they want to make a billboard, conference, whatever, they can make a proposal and be voted if the comunity wants to share the stake with that cause.
For the ones that are reading this, this happened before, in steemit, there was berniesanders and others (if you want to search it), you can counter this by downvoting their content but really only the oposite would work, as @ura-soul mentioned, comunities or the whole hive needs to be more active in this, there is Freezepeach which upvotes downvoted content like this, others should do it or join forces, consider in the future as you grow your account to dedicate HP to this kind of effort, also can be made a proposal to fund more of this.
This only happens because of the silence / inaction of many.
